Abstract

A method of operating repeaters (12, 14) or other hub devices in a local area network (5), such as one conforming to Ethernet protocol, in which there are a plurality of repeater interfaces (22, 24) of respectively different data rates for communicating with a link partner (50) on a network medium (52) comprises determining the data rate of operation of the link partner (50), and based on that data rate, automatically steering data between the network medium (52) and a selected one of the repeaters (12, 14). In a preferred embodiment, a network transceiver (16) comprises one or more physical layer devices (PHY), and a plurality of shared data busses (48) corresponding, respectively, to the speeds of operation of the repeaters, for interconnecting the repeaters (12, 14) and one or more of the physical layer devices (16; 70). A multiplexer (60) interconnects each of the one or more physical layer devices to a selected one of the plurality of busses (48), and an auto-negotiation unit (54) controls the multiplexer (60) to interconnect the physical layer devices to corresponding busses selected depending on the operating speed of the link partner.
